SHAKING ROLL.

Application filed May 26,

To all whom it may concern.

Be it known that I, GEORGE F. EGKART, a citizen of the United States, residing at Mishawaka, in the county of St. Joseph and State of Indiana, have invented new and useful Improvements in Shaking Rolls, of which the following is a specification.

This invention relates to shaking rolls which are particularly adapted to be used between adjacent bars of stripping rolls such as are employed in my tobacco stemming machine Serial No. 519,973, filed the 5th day of December 1921.

The invention is fully described in the following specification and shown in the accompanying drawings in which:

Figure 1 is an enlarged partial front elevation showing a pair of shaking rolls,

Fig. 2 is a front elevation of one of the disks composing the same, and

Fig. 3 is a perspective view of a spacer.

The embodiment illustrated comprises two parallel shafts 10 and 11 which are journaled in a suitable frame 12, and have meshing gears 13 and 14 keyed thereon so that the two shafts are driven in opposite direction and at the same speed. End collars 15 are secured upon these shafts as by means of pins 16. Disks 17 and beveled spacers 18 are horizontally placed on these shafts and the whole retained on the opposite end of the shafts by means of similar end rolls 15. The shafts 10 and 11 are provided with keys 19 which engage key-ways 17 and 18 in the disks and spacers respectively.

It will thus be seen that all the disks 17 on each shaft will be inclined in the same direction. The gears on the shafts 13 and 14: are then caused to mesh with the disks aligned as shown in Fig. 1, which forms spaces '20 therebetween. As these shafts are revolved these spaces oscillate back and forth lengthwise of the shafts.

In operation these shafts are placed one above the other between two sets of rolls in the tobacco stemming machine so that as tobacco stems pass through the spaces 20 they are given a rapid shaking action which causes any loose particles of tobacco leaves 1923. Serial No. 641,594.

to be shaken therefrom thus preventing it from being caught and drawn into the next pair of stripping rolls. To increase this separating action these rolls are preferably rotated so that the portions of the disks in contact with the tobacco stems is moving in a direction opposite from that of the stem itself which is being propelled by the stemming rolls.

lVhile I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modi fications. Changes therefore in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

' \Vhat I claim as new and desire to secure by Letters Patent, is: I

1. In combination, a pair of parallel shafts adapted to be driven in opposite directi-ons, each shaft having spaced inclined disks whereby when tobacco stems are fed through said disks, said stems are given a lateral shaking motion.

2. In combination, a pair of parallel shafts adapted to be driven in opposite directions, each shaft having spaced inclined disks whereby when tobacco stems are fed through said disks, said stems are given a lateral shaking motion, saiddisks being so positioned that each disk on one shaft is always substantially in alignment with a corresponding disk 011 the other shaft.

3. In combination, a pair of parallel shafts adapted to be driven in opposite directions, each shaft having spaced inclined d disks whereby when tobacco stems are fed through said disks, said stems are given a lateral shaking motion, said disks being so positioned that the adjacent edges of one set of disks are substantially opposite the edges of the other set of disks, whereby nearly enclosed spaces are formed which reciprocate longitudinally of the shafts as these shafts rotate.
